This invention relates to stamping or marking machines of a type similar to that shown inpat ent to Merrick dated May 31, 1910, No. 960,029.

In such machines there is a fixed frame comprising two uprights and between these is what might be called a rocker frame which includestwo pivoted arms, one being upper and theother lower, each arm being pivoted at one end to the fixedframe. v

At their free ends, these arms are connected by what might be called a head frame which is so pivoted to these arms that it will move up and down with theincarryingi fixably atg tached what maybe called a type heaidj This type head mightcarry fixed or movable, type, but the machineof Merrick carries a number of wheels around the edgesofwhich are letters or numbers. .The type head preferably in any case carries what might be called SQ table" types at the bottom. There is also preferably aninking arm which carries an pad'in such position that when the rocker frame is raisedythe pad comes in contact with the type inks them. Machines of this type may be provided merely with a feed bed upon which the blanks or tickets to be printed can be placed by hand and removed by hand but in my preferred er frame.

I accomplish this by my improved connecting device'which can betbrown out of action whenever it is desired to turn the numbering r I v p r i theparts inthe ra sed posit on.

Fig. 2 1s a vertical sectlonal view of the o wheel or wheels by hand.

ing device, it is very desirable that the feeding mechanism should be automatic and synchronized therewith. and this forms another feature of my invention.

its thetickets vary size and as it is deform of device which is'an attachment to the ly at each up anddown movem ent of the rock- In connection with this automatic number- 1928. Serial No. 275,155. 7

sirable thatdiffcrent sizes of letters or num bers should be usedin connection with them, I provide adjusting means by which the dis tance: which a'strip .ofvpaperis' advanced to form tickets; can be changed at will.

In the Merrick machine, the feeding of the stockjand the change of the numbers are both done by hand while'with my machine I can set the device for automatic consecutive numbering and'the feed for, automatically feedmg stock of different sizes. I utilize the up and down movement of the rocker frame to advance my numbering Wheel, usually one number at every cycle or complete up and down movement. The parts can besoarranged that the first or digits wheel at certain intervals will movethe next wheel or wheels which I will call forconvenience the multiple wheel or wheels. r

' To accomplish this I use an advancing arm carrying a one way pawl which engages notches inthe digits wheel. Ipivotal lyconnect the end of this advancing arm with one end of a connecting rod'which is preferably of the telescoping and elastic type, the other end of which is pivotedtothe frame in a different position from the pivots of the rocker frame. o f a By so doing as the rocker frame moves up and down the pivot on the advancing arm between it and the connecting ,rod moves through a different are from that trflcid by the moving ends of the rocker arms with the result that the advancing arm is moved back andforththereby advancing the digits wheel.

. the drawings, A represents a fixed frame having thetwo sides 1 and 2, the whole being supported on any suitable. support such as a standard 3. I

The. feedtable B is fixed in any suitable manner to the frame A. 7 V C represents a rocker frame comprising anupperarm 2O pivoted at 25 medially and extending back at 24 where it connects'with either manual orpower mechanism for rocker frame G, and a lower arm 26 pivoted to the frame at 27'. i

E represents a head frame pivoted at 120 to the free end of. arm 20 and at 126 to the free end of arm 26. It extends downward below the free end 126 of arm 26 and is formed with. or carries a'type head F which carriesany suitable type. Y i V shown; in this case, the type is carried on a pluralityof wheels 32revoluble by means of a hand wheel 31 and whichcan be locked imposition by the handles or locking pawls 30. Where the machine is operated by power it may be transmitted to a pulley 10 by belt 11 and thence by means of the shaft 13 to a small gear 14 whichengages a large gear 15 Y free to turn on .shaft19 and provided with a clutch. 16 of any'suitable type keyed to shaftlgand operable by means of a foot lever attachedtorod12 by means of which the clutch may be engaged and disengaged and I therebyactuate a shaft 19 carrying a crank 14", to the endof which one end of link 18 is pivoted. ,The other end of'link 18 is piv oted toothe end24 of arni'20 whereby the rocker frame C, the head frame E and the type head F can be moved up and down, the type being caused to engage any article 011 table 15.

4 represents an ink pad lever the function of which-is to carry the pad 5 up in contact with the type on the up-stroke as shown in Fig. 1 whereby the particular type which is set for printing is properly inked.

The above parts are all old.

It will be observed that as shown by the dotted line marked X in Fig. 1, the top of the head frame, and as shown by the dotted line Y, the bottom of the type head or the types swing over as the rocker frame descends while the inking lever moves out of the way. 7 I

It is this curved and forward motion which I utilize to actuate my consecutlve numbering mechanism.

My numbering devices indicated generally by G include one or more wheels 60, 61 on the peripheryof each of which are numbertypes and between these are the notches 63 which on the digits wheel are engaged by the back turn prevention pawl 64 which is spring pressed by a spring 65 so that itsslanting nose 66 willpermit wheel 60 to move in the direction of the arrow but not in the other clirection. This pawl 64 ispivoted to the type head F at 67. V V e L represents an advancing arm which is shown as pivoted on the same shaft 68 as the numbering wheels 60 and 61. and is so positioned that its part 140 will strike the pivot .67 and limit its backward movement while its forward .movement is limited by this same stop 67 which will be engaged by the part 147. Thereby the back and forth movement is accurately limited.

142 is an advancing pawl pivoted at 143 to the advancing arm and having a slanting nose 1.44 wh ichis caused to engage the notches 63 on wheel 60 by a spring 145. V

The dotted line Z shows the are which the pivot point 141 would make as the head frame descends, its pivots moving along the arcs X and R provided the. connecting means M was rigid. It is obvious that the distance between Z and either X, R or Y varies and this means that as the head frame moves up and down the advancing arm L with its advancing pawl 14.2 will moveback and forth and the pawl 142 willenter and leave the notches such as 63 moving the wheel 60 forward more or less according'to theadjustment.

..Tl1lS movement is limited between the stop 67 and part 147 and something must break if I did not use an elastic connecting rod.

-M representsbroadly the connecting means preferably a telescoping connecting rod between the advancing arm L and the fixed 24:7 in engagement with the cam 244opcrable by thumb piece 24550 that the hook 246Qcan be set to engage or disengagea ridge ,46 on the pivot block 417 slidable on track 42. i Pivot block 4:? is re a n d i proper po itio and is prevented from turning by screw 28 whose tip slides in groove 2&9 on t2. 1 I v This position must be such a position that when pivot block 47 is held by the latch 2 11,

the connecting means M will be compressed to less than normal length to exert a push outward on L when type head F is in the uppermost position, and that the connecting rod M will be extended to greater than normal length to exert a pull on L in the-printing position of type head F. v I

1 use a-telescoping connecting rod including the bent rod 43 which pivots on block l7 at screw 48 and which telescopes inside the tube 41 formed with the oppositely disposed slot-s 34-1 and 3&2 as see Fig. 2. Tube 41 is pivoted en advancing arm L at 141.

scoping connecting means, the extent of which can readily'be adjnsted :by moving' collars l7 and 49.

As the movement of arm L is limited by the stops 140 and 147, it will be seen by examining Figs. 1, 3 and 5 that as the head frame moves down, the advancing pawl 14:2 Will move over to the right hand position shown in Fig. 3 and when the frame rises it will move over to the dotted line posit1onthus moving the digit numbering ,dia-l one figure.

I may use a single disc like 6091 as shown,

a plurality of discs asfor instance 61 and these may be connected in any'well known way so that ten or any desired number of movements of pawl 142 wlll move .61 one digit.

As shown this is accomplished by having the notch63 in ,60as deep as the notches 163 in 61 except that two notches 263 and 363 I i 60 are deeper th n these 21 6 By thi device the lip 1 45 of -pawl .1522 will not enter the notches 163 except when flip 144i enters ot h 6 er .36 wh n will m re 6 on notch, then continne to revolve 60 without revolving 61 until the pawl 1&2 enters-the next deep notch 263 or 363 in 6 0.

The feeding means includes adjustable devices w hichcooperate with feed table B, and is indicated broadly byH, and includes atop idler feed roll 150 anda bottomknurled teed roll 15lcarried-by shaft 152 to which isfixed a ratchet 54a {llhe rack gear 50 is revoluble on shatt 152 andcarries apawl which is spring pressed to engage theteeth of ratchet 541 whereby when the rack gear is moved in one direction by the rack 51, the ratchet 54:, and therefore the positive feed roll 151 nectingarm52 which is pivoted at its upper endto-a pivot 250on a bar 53 which is slidable in Slot 58 in member 56 and may be clamped in any position thereon by means of a nut 25-1 on screw 252 which is fastened to bar '53; t

This pivot bar .53 maybe integral with the arm 20 'or ,is retained in a member 56;fixe d to the pivot 25 of arm 20. as ,by means'of a set screw 57and turns with arm 20. 7

By moving ,thepivot bar 53 and pivot 250 along bar 56, the movement of rack 51, and therefore of ratchet 5,4 and feed roll 151 can be .regulatedso as to advance the stock more or less at will.

- The extent of this movement can be much greater than if a simple'pawl was attached to arm .52 because such a direct pawl device can only engage its ratchet through a very small arc,-.while with my pawl'on the rack gear, such an arc is unlimited.
